SPARK AND CINDER TRAP.

Specification of Letters Patent.

I Patented-Sept. 18, 1906.

Application filedJanuary 31, 1906. Serial No. 298,853.

To all whom it may concern.-

Be it known that I. WILLIAM E. CARLE, a

citizen of the United States, residing at Riching adapted to be interposed in the pipe connection between the water-supply tank or reservoir and the washbasins and other fix-v tures of a car which have to be supplied with water.

The primary object of the invention is to provide means for catching and arrestingand disposing of the sparks and cinders before they reach the water-fixtures, so as to prevent the same from getting into the fixtures and grinding out the valves and valve-seats and rendering the fixtures leaky.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a trap embodying the present invention. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a horizontal section through the trap, and Fig. 4 is a vertical section through the same.

The body of the trap is preferably in the form of a quadrant, as shown at 1, comprising one curved outer wall 2 and an inner curved wall or diaphragm 3, which converges toward the outer wall from bottom to top, as shown in Fig. 2. Communicating with the space or entrance-throat 4 between the walls 2 and 3 is a nipple extension 5, which is adapted to be connected to the water-supply pipe. 6, leading from the tank or reservoir, by means of a coupling or union 7, the water being thus directed into the gradually-tapering and contracting throat 4 between the curved outer and inner walls 2 and 3, respectively.

The wall of the trap 1 opposite the curved wall 2 stands vertically, as shown at 8, and

-.at a suitable distance therefrom within the body of the trap is arranged a vertically-disposed screen 9' of meshed-wire fabric, said screen being adapted to he slid upward and downward between suitable guideslO, projecting from the opposite inner surfaces of screen 9. nipple 16, which screws downward into the the side walls of the trap, as shown in Figs. 2, 3, and 4. This screen is removable through an outlet-opening 1 1 of the trap, saidopening being circular,:as shown in Fig. 3;, and of a diameter equal to or slightly in excess of the width of the screen 9'.

erably' screwed into the opening 11. The plug 12 is removed to permit the accumulated cinders to be removed from the trap,

The openingxll is normally closed by means of a plug 12, prefand when said plug 12 is taken out the screen i 9 may be sliddownward and removed for cleaning the same.

In the top of the trap there is provided a rabbeted seat 13 in which is removably fitted the circumferential flange 14 of an inverted conical screen 15 of very fine mesh adapted to catch the finer particles or cinders which find their way'through the coarser Above the flange leis aremovable rabbeted seat '13 and clamps the conical screen 15 in place. The nipple 16 is provided with a coupling or union 17, by which it may be connected to another section of the watersupply pipe 6, as shown in Fig. 2, thus en abling the trap, as a whole, to be interposed within the water-supply pipe at any desired point between the supply-tank and the fixture or fixtures within the car. 4

The cinders which accumulate in the wapassing through the water-supply pipe 6 are carried between the converging-walls 2 and 3 and directed againstv the coarser screen 9, which arrests their onward progress and causes them to fall into the bottom of the trap. The finer cinders which pass through the screen 9 are caught and arrested by the conical screen 15 and are also deposited in the bottom of the trap. Periodically the plug 12 may be moved and the accumulated cinders taken out of the trap. The screen 9 may also be removed and cleaned, and by means of the construction described the finer sceren 15 is also made removable through the top of the trap by removing the nipple 16. .The ,trap effectively prevents the cinders from reaching the valves of the Water-fire tures in the car, and thereby prevents the grinding out of the valves and valve-seats, adding materially to the life of the fixtures.

I claim' 1. Atrap embodying inlet and 'outlet openings, an upright screen interposed between said openings, convergent walls leading toter-supply tank or reservoir (not shown) in Ward said screen, and a conical screen at the opposite side of the'fiIst-named, screen fromv the deflecting-walls, said conical screen guarding the outlet of the trap.

2'. A trap for the purpose described provided with an opening in the bottom thereof, a plug for c osing said opening, a vertically- .disposed' screen extending from top to bottom of the trap and removable through said opening, converging and deflecting walls leading toward said screen, and an inverted conical screen located at the opposite side of the first-named screen and guarding the outlet of the trap'.

3. A trap for the purpose described comprising inlet and outlet openings and provided with a cleaning-opening in the bottom thereof, a remo able screen extending from top to bottom of the trap-body and removable through the cleaning-opening, convergscreen, and a removable inverted conical screen of finer mesh guarding the outlet of the trap and made removable therefrom.

In testimony whereof'I aflix my signature in presence of two witnesses.
